' his invention relates to locks vandfmore.

-parti'cnlarly to motometerloclrs.,

It is a purpose of the invention to providey means for locking a cap on a radiator nipple,

said'cap being adaptedto carry an'V indicatmg instrument, such as a motomet-er.

It is a further purpose ofthe invention to provide key operated means mounted in j against :relative turning movement.

It.isanotherand further object of theiin-' vention to provide. means'for locking a radiator :capi to a radiator ,nipples thatfiOml prises a Vmember' mounted for'rotationv in, l one of said members ,andV adaptedjto enter av recess vin a ypart rigid withfthe other; of said members, so Vas, to Vprevent rotation of relative to said radiator nipple, said rac Aiator cap 'and part rigid with the "nipple being provided with cooperating formations thatV are adapted to Vbe moved into and out of position to hold said cap onI said j nipple by Vrotationl'of said'lzcap rel'ative'to said nipple. d Y Y. .t

It isfalsoa purpose of the vinvention to rovide means vfor securino' ya radiator can P e 4 i to a radiator VVnipple T nembe'r Vcomprising a projection onY one of said members adapted to enter a groove in the othery of said membersyand adapted .tobe secured thereinby a turning, of said cap relative to said nipple, said projection and said groove having cooperating `.wedging' faces for drawing said cap down `on said nipple `and compressing a gasket between said'cap andnipple member.

' It is still a further purposeof the inven-V tion toprovide means forsecuring a motometer to aradiator comprising a cap adapted to carry a motometer or other measuring instrument,and a member securely mounted on fthe' radiator nipple,v said lastfmentioned men'iberv being provided with a groove and said cap-being Vprovided with val projection adapted to enterV said groove `Vby moving said cap axially 'relative tosaid member and to be retained in said groovebyturningsaid cap relative to said"T member through an arciA of substantiallySO". {'It is also a purpose` ofthe invention yto vprovideV means for lock# ing'sardjcap agan'ost rotation relative to s id membercompi-ismga key operated i, mber Y against Arotation relativel thereto.'

Yand imen'iberA sogas to vprovide a watertight i `broken away v adaptedv to cooperate;

' -It is still anotherfobj ectofthe `invention toy provide; interengaging `wedging faces on 05 said cap fand themember on said nipple so asrto drawsaid cap jtoward said member and compressa resilient gasket between said v'cap fit forsaid cap.Vl `The purpose of this isto 70 assure a watertight fitandyyetfatthe `saine timeliave the Aley receivingV portion ofthe' lock always in the rsame relative position to said 'radiator when' said Vcap is in locked position, preferably facing thefront. y
